I have a SN30 Pro (wireless). Its a good pad, not the most ergonomic, but its well built and works well. Its just a quality SNES pad clone with extra flat 'trigger buttons' LT/RT. Works pretty well, I prefer it to the SNES Classic controller which says a lot about its quality.
If you can afford to bump it up for the Series S/X controller, I would probably go that way. Way more robust and ergonomic and 100% compatibility with Windows and games that support a game pad. You should be quite easily find one available to buy on Amazon next month upon the new console launch. All you need is a USB-C cable to plug it in and you're golden. Or connect via Bluetooth.
